Things I liked:Adjustable objective, screw on lens covers, extreme adjustable range on tall turrets. This is one of the nicest air rifle scopes I have come across. Put it on my .22 Ruger Yukon, and can put a pellet on target at 15 yards, same hole all shots.Things I would have changed:Nada.What others should know:Variable power air gun scopes are, in my opinion, a waste of mechanical features. This 4X scope is perfect power for my backyard / garage target shooting. Dialing in a clear picture at close range is good.
